11) The SYNC command helps to improve accuracy. It has been my personal experience that it is best to center the object BEFORE selecting this command. THEN, when at that menu choice, press ENTER to confirm, then repeat the process once more. I don't know why, but, using the SYNC command TWICE works better than only once. The first few objects usually require this proceedure. If you later find something placed near the edge of the FOV, then use the SYNC command again.




Leaving "sync" out of the mix, how _is_ go-to accuracy? On average from horizon to horizon?

Over all, not too bad. However, I've made such a habit of doing a few sync functions first that I'm not completely certain. I do know that the more accurate the initial alignment the better it is.

Steve,

How quiet is the Mini-Tower?

I am used to the peace and quiet of the Atlas. How does the M-T compare?

Thanks,

Ron

Is "not too bad" 10'...15'...30'?

I ASSUME (and you know what they say 'bout that word) all objects are not landing in the field horizon to horizon or you would not be using sync?

Ron:

The sound level is closer to my Atlas than it is to my silenced CG-5GT. Not quite as quiet as the Atlas, but, it won't scare the neighbors or the cows, either! LOL

Rod:

I will need to make a test run without using the sync command before I can give you a good answer. Like I said, it has become a habit to use it so I don't really know.

Tom:

I agree that the tripod seems a bit light. However, I have not had any issues with flexture, yet. For its size it is quite stabile. I need to really load it up to see what it can take. Unfortunately, we've got more rain coming tonight!! ARRRRRRRRRGH!!!

What are the alt and az locks suppose to do? Is this just for manual movement or storage?

The clamping knobs are indeed for locking the axles. The motors will drive the mount to any position that you wish. You can use it manually, but, the alignment will be lost if you do so.

It's quiet. At 10' I can tell if it is slewing. 15' I can barely hear it. At 30' I cannot hear it at all. Your experience will vary depending upon just how sensitive your hearing is and what background noises are present.

Does that help?

Welcome back, Steve.
About the GPS, I found a few times, maybe it was coincident, when I purposely changed the W to E (in order to make the setting far away from my location), the indicator changed from "on" to "ok" right away. I suspect that if the location is too close to the setting in the controller, the GPS does not bother to update.
About iOptron customer service, I feel it is super. I called once regarding the goto accuracy, the person guided me step by step and solved my problem on the phone. The problem was that I did not check the daylight saving mark, which made it one hour difference.
Jason

Jason:

Thank you very much. I've not encountered that issue with the GPS. I have noticed that once it knows where it is located that unless enough time has passed for new birds to be readable the GPS "OK" comes on pretty quickly.

I am glad to hear that the service folks were able to help you out and that you are pleased with the results.

Re: iOptron Mini Tower - Using the Supplied CW new [Re: Telescopeman54]
      #2620930 - 09/03/08 09:49 AM

Steve,

I had some questions concerning how to use the CW that were addressed by the folks at iOptron (hopefully in the future this info will be included in the manual). Of course, there is absolutely nothing wrong with using the balancing method outlined earlier with the CW in this thread to verify the weight has the proper compensation, it just seems that for lighter scopes, its not necessary:

Hi Sam,


Thanks for your feedback. Noted.


Regarding the counterweight – the unit can support 10lbs without a counterweight. So even if you did use a counterweight the exact position would not be critical.



Hope this helps.

Great!

About balancing for the mini, 10 lb OTA or below is not necessarily needed to add a CW; the design itself has compensated the weight. However, it will be better to have the balancing rod attached without the CW. For heavier OTA, the CW definitely helps. Yes, the included CW at the far end for the heaviest ones and any place between for other weights. Since the mount can carry at least 10lb without counter, so it is not critical to precisely place the CW at its counter torque position.

I dont' have a scope that weighs under 15 pounds! LOL

That is good information and I am certain that others with lighter OTAs will benefit from your note.

Thanks and clear skies.

Steve,

Well I only own little wide field scopes, not Howitzers like yours !

Steve and/or Tom,

By the way, I tried to open up the backside of the mount to check the GPS connections and got all of the allen head screws off but how do I get the cover over the big altitude piece that you screw the CW bar into ? Do I have to remove the 4 big allen bolts from the other side and then pull it apart ? I did get the top off and did push on the small multi-pin connector although it looked okay to me and the RF connector to the antenna also looked fine. I just put the top back on and will get it out again tonight to see if the GPS says its acquired the satellite signals or not. I just want to make sure there isn't anything I can do to make it work right before I go and send it back.

Thanks,

Sam

      #2623762 - 09/04/08 03:01 PM

Sam:

The most likely problem will be the small gold connector on the GPS module. Just use a pair of needle nosed pliers to give it a twist. Just as if you were tightening the lead from a cable TV connector. It doesn't take much to set it.

If you think that you need to remove the side cover to check the GPS lead then follow this proceedure. First, remove the CW shaft. Then, just unscrew the clamping knob until it comes off. The cover will then be easy to remove. BE CAREFUL! The cable lead to the GPS is SHORT! It is the one at the top. The two wire lead set below it is for the internal battery pack. The other two lead sets are the motor controls. Those are at the bottom of the board. Just push the GPS connector down firmly and then button everything up again.

On the GPS module there is a small white connector that may be lose. UNDERNEATH the module there is another connector that has shaken lose on one unit, so far. The most common issue though has been that gold connector.

Two things to note are that on the next production run, the gold connector will be held from backing out with a small dab of RTV. The other is that the GPS lead will be about 1 inch longer to prevent strain on the cable during shipping. These small changes should prevent any further issues with the GPS module.

By the way, someone had asked about getting the battery pack lose from the compartment. It is a bit of a tight fit so I've just used my multi-tool needle nosed pliers to grab the center of the battery pack and wiggle it lose. Be careful not to pull the lead back to far as this may cause it to become diconnected. I just lay the pack on the edge of the compartment and then install the batteries. It's then a simple process to wigle it back into place.

Let me know if I can be of further assistance.

I believe my issue with the connections had to to with the gold RF GPS cable at the top of the unit. Although it started working when I shoved it in a bit more, later use of the mount showed that it had stopped again. I suspect I nudged it when I put the cover back on. Taking it apart and reconnecting it entirely made the unit acquire a lock quite rapidly, and I've done that this time - we'll see if it holds.

I think most will find it a very nice mount - particularly for smaller telescopes, but the settle times are a bit too long for me with - say, a 4" apo and a 3" apo mounted side by side.

The tripod is a vast improvement from the previous unit, but they could definitely benefit from one with 2" thick legs.

I have found their user group (and support) be quite good.
